<\/a><\/p>\nNote the shape of the bottle: It’s a bit thinner and taller than the 20oz bottles common in the US. On our drive to the airport Saturday night, we stopped at a gas station in order to get coffee to keep David awake and all of us alive, and I got some 7 Up for myself. It tasted slightly different from what I remember from the States, though I don’t know when I last had any actual 7 Up. I finished it in the Morelia airport while waiting at the gate, after the baggage-searcher said I should drink it before boarding the flight (not that it would really matter). I tossed the empty bottle in my backpack as a souvenir. (I had considered swiping the Spanish Coke can from the flight in, to complement the Swedish one my dad brought home from a business trip.)

The top has been on tight ever since Mexico, and I still haven’t opened it even now, perhaps in case I ever need a sample of Mexican air (not to mention a nice example of physics in action). I pondered why this might have happened for a few minutes, and then asked my dad what he thought. He asked one question, and I suddenly realized what was going on. I wonder, how many of my readers are astute enough to figure it out? (I have no doubt that my physics and engineering friends at RIT will have no trouble with this.)<\/p>\n","protected":false},"excerpt":{"rendered":" While we were touring Acuitzio on Tuesday, our guide Moi was nice enough to buy us drinks from a store we passed by.
